Abstract

A filter apparatus having an identification and filter subassembly. The identification and filter subassembly includes a bag filter and a top end collar and a radial identification tag. The collar has a lower portion fixedly connected to the bag filter, and has a middle portion to be supported within a vessel, and has a top lip portion to engage a cover plate of the vessel. The collar has a pivotable web portion disposed between the middle portion and the top lip portion, and has an inner surface with a groove having sidewalls. The identification tag is cantilevered radially outwardly from the top lip portion for reading information disposed thereon from the exterior of the vessel.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A filter apparatus comprising: an enclosure subassembly having an axis and having a housing with a top flange and having a cover plate connected to the housing;   a basket subassembly having a basket portion and having an annular ring in sealing engagement with the top flange;   an identification subassembly having a filter bag and an integral collar in sealing engagement with the annular ring and with the cover plate;   said collar having a lower portion fixedly connected to the filter bag and having a middle portion supported by the annular ring and having a top lip portion engaging the cover plate;   said collar having an inner surface with an inner groove having a lower sidewall disposed adjacent to the middle portion and having an upper sidewall disposed adjacent to the top lip portion;   said collar having a pivotable web portion disposed between the middle portion and the top lip portion;   said identification subassembly having a cantilever identification tag fixedly connected to the collar; said identification tag having a face which contains information related to the apparatus, wherein the tag is connected to indicating means for signalling the presence of the filter in place, and wherein the indicating means is a slot through which the tag passes and an electrical switch for indicating the presence of the tag in the slot.   
     
     
       2. The apparatus of claim 1 wherein the collar has at least one elongated handle and a radial inner face; and   the handle having opposite end portions, each end portion having an arcuate flexible connection to the radially arranged inner face.   
     
     
       3. The apparatus of claim 1, wherein the tag and the collar are composed of a molded thermoplastic rubber. 
     
     
       4. An identification and filter subassembly for an enclosure subassembly having a cover plate comprising; a filter bag having a top end portion of ring shape; and   a collar having a lower portion fixedly connected to the bag top end portion and having a middle portion supported by the enclosure subassembly and having a top lip portion engaging the cover plate;   said collar having an inner surface with an inner groove, said groove having a lower sidewall disposed adjacent to the middle portion and having an upper sidewall disposed adjacent to the top lip portion;   said collar having a pivotable web portion disposed between the middle portion and the top lip portion;   said top lip portion having an identification tag cantilevered from the top lip portion;   said identification tag having a radially inner portion fixedly connected to the top lip portion;   said identification tag having an upper face;   said upper face having indicia for showing information related to the identification and filter subassembly, wherein the tag is connected to indicating means for signalling the presence of the filter in place, and wherein the indicating means is a slot through which the tag passes and an electrical switch for indicating the presence of the tag in the slot.   
     
     
       5. A filter apparatus comprising: an enclosure subassembly having an axis and having a housing with a top flange and having a cover plate connected to the housing;   a basket subassembly having a basket portion and having an annular ring in sealing engagement with the top flange; and   an identification subassembly having a filter bag and having a collar in sealing engagement with the annular ring and with the cover plate and having an identification tag cantilevered radially outwardly from and fixedly connected to the collar, wherein the tag is connected to indicating means for signalling the presence of the filter in place.   
     
     
       6. The apparatus of claim 5 wherein the collar has at least one elongated handle and a radial inner face; and   the handle having opposite end portions, each end portion having an arcuate flexible connection to the radially arranged inner face.   
     
     
       7. The apparatus of claim 5, wherein the tag and the collar are composed of a molded thermoplastic rubber. 
     
     
       8. The apparatus of claim 5, wherein said collar having a lower portion fixedly connected to the filter bag and having a middle portion supported by the annular ring and having a top lip portion engaging the cover plate; said collar having an inner surface with an inner groove having a lower sidewall disposed adjacent to the middle portion and having an upper sidewall disposed adjacent to the top lip portion; said collar having a pivotable web portion disposed adjacent to the top lip portion; said collar having a pivotable web portion disposed between the middle portion and the top lip portion; and said identification tag having a face which contains information related to the apparatus. 
     
     
       9. A filter apparatus comprising: an enclosure subassembly having an axis and having a housing with a top flange and having a cover plate connected to the housing;   a basket subassembly having a basket portion and having an annular ring in sealing engagement with the top flange; and   an identification subassembly having a filter bag and having a collar in sealing engagement with the annular ring and with the cover plate and having an identification tag cantilevered radially outwardly from and fixedly connected to the collar, wherein the tag is connected to indicating means for signalling the presence of the filter in place, and, wherein the indicating means is a slot through which the tag passes and an electrical switch for indicating the presence of the tag in the slot.   
     
     
       10. The apparatus of claim 9 wherein the collar has at least one elongated handle and a radial inner face; and   the handle having opposite end portions, each end portion having an arcuate flexible connection to the radially arranged inner face.   
     
     
       11. The apparatus of claim 9, wherein the tag and the collar are composed of a molded thermoplastic rubber.
